README
README.mdAutonomonomous car by C++, I hardly know her
A school project building autonomous vehicles that drive themselves along a walled track about 1 m wide. The firmware is written in MicroPython for an ESP32-family board. Each vehicle uses three time-of-flight distance sensors to stay centered between the walls, a Pololu Motoron motor controller, and a start module that tells it when to go.
Code
| Folder | Vehicle | Description |
|---|---|---|
| snok_1.2 | RC car | Ackermann steering with a servo and one drive motor. Detects when it is stuck and reverses out |
| huggorm_1.0 | Tracked chassis | Excavator with two tracks, steers by the speed difference between them |
Each folder is a complete firmware. To run one, copy its config.py, main.py
and lib/ to the board, for example with Thonny. All tunable values are in config.py.
Components
- VL53L4CX ToF lidar sensor – left and right side sensors
- VL53L0X ToF lidar sensor – front (middle) sensor
- Pololu Motoron M2T550 dual I2C motor controller
- DC-DC step-down converter (1.23–30 V, 1.5 A)
- Slide switch (on-on)
- GT Power B3 battery charger

Questions
How big is the Self driving car PCB?
It measures 100 × 75 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Self driving car use?
15 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Self driving car KiCad files?
From the aggeazagge/cppIHardlyKnowHer repository on GitHub, at the commit this page was made from: the board is Hardware/Self_driving_car_kicad/Self_driving_car.kicad_pcb and its schematic Hardware/Self_driving_car_kicad/Self_driving_car.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Self driving car design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
